摘 要:针对基于吸气式高超声速飞机拦截平台的临近空间高机动目标中制导拦截问题,开展了在线中制导律设计方法研究。考虑到高超声速拦截平台的气动/动力耦合特性与吸气式发动机工作状态约束,设计了一种双层在线中制导律,顶层以前向拦截中末制导交班条件作为末端约束,以比例系数、油门为优化变量,燃料消耗为性能指标,采用高斯伪谱法阶段性在线规划拦截轨迹,底层采用轨迹线性化控制方法实现轨迹剖面跟踪制导。通过仿真分析验证了轨迹设计及制导方法的有效性,并与传统比例导引法进行对比仿真,验证了该中制导方法的优越性。Aiming at the interception midcourse guidance problem of high maneuverable targets in near space based on air-breathing hypersonic aircraft interception platform,the guidance law design method in online interception is studied.Considering the airframe/scramjet integration coupling characteristics and working condition constraints of high intercept platform,a dual level online interception guidance law is presented.At the top level,Gaussian pseudo-spectral method is used to plan the intercept trajectory online in stages.The handover conditions of midcourse and terminal guidance are used as the end constraints,with proportional coefficient and throttle as optimization variables and fuel consumption as performance index.At the bottom level,trajectory linearization control method is used to realize trajectory tracking guidance.The effectiveness of the trajectory design and guidance method is verified by simulation analysis.The superiority of the guidance method is verified by comparing with the traditional proportional guidance method.
